Slow Poke Galaxy Ace IIX

I have a galaxy ace IIx phone and it is very slow. The texts take a while to send and when I go in my contacts, they take a while to load. I don't have much on my phone at all. Can anyone help me to make it fast again.

Hey carole,
try checking on Samsung web site to see if there is any software upgrade for the phone you have, also try saving all your data (contacts, pictures, videos, texts, emails etc)on your PC or Laptop and do a factory reset on your phone
as well take a look on the apps you may have downloaded and check on the reviews to see if any of them will make your phone run slow
check on the settings of your phone the status of the memory , and look for the running services , some apps will run in the background even though you are not using them and will cause your phone go slow
